rIhis is a division of my copending application for Letters Patent `ofthe United States,Serial No. 339,470, filed February 12, 1929, forimprovement in viscose treating apparatus. l y

My invention relates to apparatusof the type claimed in Letters Patentof the United States No. 1,616,918 granted to me February 8, 1927wherein arotary `Carriage is arranged to support a circular` series ofreceptacles, each adapted to receive trays of viscose filaments', andliquids for treating them; said carriage being turned to successivelysubject such filaments to the action of the different liquids, which aresuccessively supplied to and discharged from said receptacles by theautomatic operation of series of valves.

The form of my invention herein .disclosed differs from thatfof saidLetters Patent, in that bodies of the several liquids aforesaid arecontinuously maintained in respective stationary tubs, and the rotarycarriage is arranged to support the filament trays independently of theliquid containers, and to not only intermittently turn to present thetrays in registry with such stationary tubs, in succession, but to belowered and raised to successively submerge the filaments in the liquidsin said tubs and raise the filaments therefrom. As hereinafterdescribed, the means for raisingand lowering said-carriage is adapted torepeatedly dip the filaments up and down in the liquids inthe tubs, tocause the liquids to surge through the filaments inthe tubs. f.

The several features of my present invention, differing from thatdisclosed in said Letters Patent, are advantageous in that the cost ofconstruction of the apparatus is very much less and the operationthereof is facilitated.

My invention includes the various novel features of construction andarrangement hereinafter more definitely specified.

In said drawings; Fig. I is a plan view of said rotary carriage, thecircular series of tubs subjacent thereto, and their appurtenances.

of the electric ciring viscose` filaments, a circular series of eighteentanks or tubs 1, for containing liquids, is so organized thattreatmentof the filaments may be effected during a cycle of operation.of the apparatus. The filaments to be treated may be convenientlyheldin trays which may be supported upon a Vpair of opposed angle rails2, which are convenlowerlng sald rotary meeheientlyformed of porcelainor other ceramic material. vEach pair of such rails 2 issuspended byhangers 3, which` are pendent from tray supporting frames 5 which arepositively fixed upon the rotary carriage 65, which is rigidlyconnectedwith the vertical shaft 66 by which saidcarriage and itsappurtenances, including the trays of filaments,

are raised, lowered, and turned from tub to tub in the circular series.

Referring to Figs. II to V; said rotary carriage shaft 66 is mounted forrotation and 4vertical .reciprocation in the bearing 71; which bearingis in the stationary housing V72 and has the lubricating oil Vpocket 7 3above it and the felt packingt below. it, tolimit leakage of the oildown said'shaft. Said shaft is also mounted for rotation and verticalreciprocation in the bearing bracket 75 von the basepiate 76 which isstationary on ay scaffolding 77. Said base plate 76 has the rollerbearing 80 for said'shaft and supports freely in the roller bearings 82and 83 betweejn said bracket 75 and base plate 76."y Said gear 81 has akey 85 exten-ding in the key way 86 in the portion of said shaft 66which reciprocates through said worm gear i 81; whereby said shaft maybe turned without interference with its vertical reciprocation.

Vthe worm gear 81 which is mounted to turn Said rotary carriage shaft 66has the collar 87 rigidly connected therewith and by which it is raisedand lowered by means of the lever 88 which is fulcrumed at 89 on thebracket 90 rigidly connected with said base plate l76. Saidlever 88includes the fork 91 carrying opposite rollers 92 upon which said shaftcollar 87 continually rests. The weight of said shaft 66 and itsappurtenances including said carriage 65 etc., is almost completelycounterbalanced by the weights 94 which are carried by the link 95 atthe end of said lever 88 opposite to said shaft 66. The weight of saidshaft and its appurtenances, not thus counterbalanced, is borne by therotary cam 96 which is ridden by the rollers 97 on'saidl lever 88. Saidcam 96 is of such configuration that every desired vertical movement ofsaid shaft 66 and the filament carriage supportedby it, 'is effected inproper sequence with `the intermittent -rotary movement of said shaft.The relative rotary movements of sai-d shaft 66 and cam 96 areconveniently 'eected by the driving shaft 99 which may be constantlyrotated by connection with a suitable motor and which has, rigidlyconnected therewith, the crown clutch member 100. Intermittent rotarymovement of said shaft "66 and cam 96 is obtained from the continuousyrotary movement of said shaft 99, by means of the crown clutchmember-101, which is mounted to slide axially upon the shaft 102 whichis journaled, in axial aline- `ment with said shaft'99', in the bearings104 and 105 on said base plate 7 6.y Axialy movement of said clutchmember 101 to engage Vand disengage said clutch member 100, is

effected by the lever 107 which is fulcrumed vat 108 on said base plate7 6,`has a stud v109 engaging the groove 110 in said clutch member 101,and is connected by the link 111 with the lever 112 which isl fulcrumedat l113. S'aid lshaft 102 carries the worm 115 continually engaged withsaid worm gear 81,

whereby said carriage shaft may be intermittently turned; when ,saidworm is operatively connected with its shaft 102 by its friction clutch116, as hereinafter'described.

Said shaft 102 also carries, rigidly connected therewith, the worm 117,continually engaged with theworm gear 118 on the ,cam shaft 120 lwithwhich said 'cam 96 is rigidly connected The construction and arrangementof the driving mechanism aforesaid vare such that said cam shaft 120 iscontinually turned clockwise as indiacted in Fig. III, and the carriage65 4is turned clockwise vas indicated in Fig. I, whenever the clutchmember 101 is engaged with the driving clutch y member 100 on the shaft99.

Said cam shaft 120 carries the cam 121 having the roller 122 incooperativerelation with the clutch'lever 123 which is mounted on therock-shaft 124 journaled in the bearings 125 and 126 which arestationary on said `121 to intermittently encounter said clutch lever123, push it `down out of they path of said roller 122, .and thus movesaid clutch member 130A to the right in Fig.v III, thusV engagingsaidmclutch member 116 to frictionally engage said worm 115 withv saidshaft 102 to effectthe'intermittent turning movement of said carriageshaft 66, at the Vproper time in the cycle of operation of said carriage65 Said clutch'lever 123 also has the roller132'whichrides upon thevannular flange 133 of said clutch member 116 andis adapted to drop intothe notch 134 of said disk when said clutch member 130 is in thedisengaged position shownin Fig. III. The construction and arrangementof'the'various elements aforesaid bywhich'said flange 133is turned, aresuch that when its' notch 134V is thus engaged by the clutch leverroller 132; the porcelain rails 2carrying the filament trays, are inregistry with the respective tubs 1, in which said filaments are to bedipped.

However, as a safety device,'to prevent accident-al lowering of thecarriage 65 and its appurtenances when said tracks 2- are not in properregistry withsaid tubs 1 Iy provide the slide bolt V136 which is mountedto reciprocate horizontally in the bearings 137 and is operativelyconnected with the arm 138 of said clutch lever 123, by the bell-cranklever 139 and link 140; sothat, whensaid roller 132 is uplifted from thenotch 134 of the clutch-flange 133,7said bolt 136 is thrust away fromthe observer in Fig. III and be- Y neath said lever 88 so astofupholdtheV latter and the unbalanced Vportion of the weight of thecarriage 65v and its appurtenances until said roller 132 falls into saidnotch134,

when the latter is vagain presented in registry therewith. Said slidebolt 136 thus prevents lowering movement lof said carriage65` and its'appurtenances except vwhen the porcelain tracks 2 are properlyregistered with their respective tubs 1. i i

Moreover, I prefer to provide said apparatus withy means toautomatically stop the operation of the machineby the shaft 102;

if and when said roller 132A fails to drop into the notch 134-oftheclutchflange 133 at the l proper time. Such means 'includes the arm 142on the clutch lever 107 and the weight 143 which, when released, dropsupon said arm 142 and shifts'the clutch member 101 to the left in Fig.III, by said lever 107. Said weight 143 is Vconveniently upheld by thesolenoid coil 144 which is energized by'l kthe circuit including theconductors '145' and 146. Said circuit includes the two push switches v*148 and 149vwhich are spring pressed so' as to be normally closed, inparallel relation with each other but in series with said coil 144. Aslong as either of said switches remains closed, the circuit energizingsaid coil 144 is closed and t-he weight 143 upheld. Either of saidswitches may be pushed to open the circuit thereat, without dropping theweight, but if both switches are contemporaneously operated to open thecircuit, said weight drops and the machine stops. Said switch 148 isarranged to be operated by the lever 151 which is rigidly connected withthe rock shaft 124, so that the circuit is opened at said switch 148whenever said roller 132 is uplifted from the notch 134 to roll upon theclutch flange 133 as the latter turns. The switch 149 is arranged to beoperated by the roller 152 on the arm 153 which is rigidly connectedwith the cam shaft 120. Said arm 153 is so positioned on said shaft thatsaid roller 152 pushes upon the switch 149 immediately after said notch134 has been presented in registry with said roller 132; so that, if theswitch 148 has not been permit-ted t0 close by the fall of said roller132 into sai-d notch, and consequent withdrawal of the arm 151 from saidswitch 148; the circuit remains open at that switch and is, thereupon,immediately opened at the other switch 149, so that the circuitenergizing said coil 144 is broken and the weight released to stop theapparatus as aforesaid.

As the action of the worms on said shaft 102 tends to thrust the latteraxially to the left in Fig. III, the bearing 105 includes anti-frictionballs or other rollers to sustain such stress and minimize the frictionincident thereto. Moreover, I find it convenient to lubricate the lowerend of the shaft 66 and the worm gear 81 and worm 115 connectedtherewith, by mounting upon the under side of said base plate 76, theoil well 156 into which the lower end of said shaft 66 dips and forcesoil upwardly, to said parts, each time said shaft is lowered.

However, I do not desire to limit myself to the specific constructionand arrangement herein set forth, as it is obvious that variousmodifications may be made therein without departing from the essentialfeatures of myY invention, as defined in the appended claims.

I claim:

1. The combination of a vertically movable carriage; means toautomatically intermittently raise and lower said carriage; means toautomatically intermittently turn said car- 5 whereby said carriage israised and lowered by rotation of said cam.

2. The combination of a vertically movable carriage; means toautomatically intermittently raise and lower said carriage; means toautomatically intermittently turn said carriage; wherein the means toraise and lower said carriage includes a cam having a plurality ofcrests, and wherein said carriage is carried by a verticallyreciprocatory shaft; a collar rigidly connected with said shaft; a leverarm fulcrumed on an axis at right angles to the axis of said Y verticalshaft; roller means on one end of said lever arm bearing against saidcollar; means at the other end of said arm almost counterbalancing theweight of said vertical shaft and its appurtenances; whereby saidcarriage is raised and lowered by rotation of said cam.

3. The combination of a vertically movable carriage; means toautomatically intermittently raise and lower said carriage; means toautomatically intermittently turn said carriage; wherein the means toraise and lower said carriage includes a cam having a plurality ofcrests, and wherein said carriage is carried by a vertical reciprocatoryshaft; a collar rigidly connected with said shaft; a lever arm fulcrumedon an axis at right angles to the axis of said shaft and lbearingagainstsaid collar; means carried by said arm for cooperation with saidcam; and carriage turning means including a worm gearing operativelyconnected with said cam by a clutch, and including another eccentric,arranged to turn with said cam, and effect intermittent operation ofsaid clutch.

In testimony whereof, I have hereunto signed my name at Burlington, NewJersey, this third day of August, 1932.
